Just learn jquery, in doing a checkbox to select all the time encountered a problem, using the attr () method, you can only successfully select and deselect all the time, the second is not, such as the following

$("#chkAll"). Click (function () {if( This.checked==true){                $("#tab input[type= ' checkbox ']"). attr ("checked",true); }Else{                $("#tab input[type= ' checkbox ']"). attr ("checked",false); } })

After searching the net, found the solution, is to change the attr () to prop ():

$("#chkAll"). Click (function () {if( This.checked==true){                $("#tab input[type= ' checkbox ']"). Prop ("checked",true); }Else{                $("#tab input[type= ' checkbox ']"). Prop ("checked",false); } })

The 1.7.2 version of jquery can be used attr, but then can only use prop, for a moment to understand it first ....
